STFFER.

Application filed october s, i921, semi N5, 506,274..

To all whom t may concern Y y Be it known that I, CHARLES W. HorrvMANN, a citizen of the United-States, residing at Philadelphia7 county of Philadelphia, State of Pennsylvania, have inventedv a new and useful Stuffer, of whichv the following is a specification. v

The object of my present invention is to devise a novel construction and arrangement of a stuffer wherein the material. will be fed continuouslyfrom the stuifer under a substantially uniform pressure. Other objects of my invention` are to vcan be maintained in a sanitary condition andfwherein the material is fed under pressure to a rotary stuffing element which -will effect the Adischarge from the stuffer of a predetermined quantity of material.

l With the above and other objects in view which will hereinafter appear my invention comprehendsa novel construction and arrangement of a stuffer. Y

Y vIt further comprehends a novel construction of a stuffer having a casing provided with a novel construction and arrangement of agitating and scrapingmembers and from which the materialis discharged to feeding mechanism which feeds the. material under ypressure through a restricted port into .a

chamber communicating with the discharge spout and in which is contained anovel con-` struction of material delivering mechanism. Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description. y

. For the purpose of illustrating invention, I have shown in the accompanying drawings'l a typical embodiment thereof which is at present preferred by me since this embodiment will be found in practice to however, to be understood 'that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalitiesV asl herein yshowny and described. .y v -1 Figure 1 representsl a top plan view of a stuiler, embodying my invention.

2 designates ythe. driving shaft'which is ,f' provided with'a pulley 3 `in order to adapt it to be drivenvby any desired source of communicating with a chamber '10 of the feed casing 7. The feed chamber. lO'has one of its walls in lproximity to the discharge opening 9 inclined or bevelled, as indicated` i at 11,"see Figurej The "feed" shaft Gl'lias moiintedon it in' the feed ."chamberf10 .a helical blade 12 jwhich ser-ves as a'conveyor y and which' at its forwardend'` closelyts' the reduced bore 13 of thefeed chamber 10,"s`o

The feedjehambefic tits reward end is 90" if of enlargeddiameter, as seen at 14;, andthe chamber thus -formedfis Separated from the main body portion vofthe feed c'hvamberl'O by means of a stationary partitionv l1 5 'which' isin the form of a ring segment having its ends spaced from each other,v desiredfdischamber 10a dischargeport 16. The'zfeed shaft has keyed to it at its forward end a i A 4tance to kformflwithV the wall-fof lthe feed i give satisfactory andvrel'iablev results. It is,

lspout 19, the bottom wall. of which in prox-Vvv i imityv to the' stluffinglmember 17 is inclined downwardly andy outwardly, as at 20,'and i then turnedfupwardlyl as at 21. L y l v22 designates avblade fulcrumedjatv23fand having "itsjforward end adaptedjto, rideon the reisinfo-Lith?. fsfiiueemmberflllerd' ioo riphery a plurality of bladesv1'8,seemore parf iok be retained thereagainst by means of a spring- 24., The casing 8f has disposed centrally within it a. bearing sleeve which flanged at its lower end in order to adapt it to be connected' to the lbottom of the casing 8 by means of fastening devices 26. rlhe sleeve carries at its upper end a bearing 2 through which passes a shaft 28. the lower end` of which is mounted in a. 'step bearing' 29- i designates a' worm gear which meshes with a worm, 31 on the driving shaft '2. Secured to the shaft 28 by means of a key 32 is anl agitator' and scraper 33 having vertically disposed blades 34 which at` their botto-rn are laterally deflected, as at 35, to ride on the bottom ofthe container 8 and the laterally extending portions 35 areupwardly deflected as atBG, so that; they extend the desired disy tance above the container 8. The forward end of the feedv chamber 10 is closed by means 0f a clnsure?.

The operation of` my novel stuffer will now be apparent and is as follows Thematsial to be stuffed is placed in the container 8 preferably during the revolution ofthe,drivingshaftQ. The worm 31 and the worm gear 30 cause the shaft 2Sy 4to itei?ol v.e,antl thereby thev agitating and scraping members which canse the material in the ycontainer 8 to feed towardsand into the discharge opening 9, and therethrough into the feed chamber l0. Thefeed shaft 6 V which is intergeared with the driving vsha-ft 2, causes the-material to beA fed forwardly in the feed chamber l0 into the restricted bore 1,3. s Qtha-t the desired, pressure is created, on such material and the material then passes through ythe port 16 i into the chamber formed.- between the blades-*18, the periphery ofthe stuffing member 1.7 and the juxtaposed wall of the casing.,

Each blade I Sfduning.v its revolution brings al predetermined amount of, material into the dischange spoutvl). and therefrom, into the V,casing which` is to be stuffed the`V casin r be- YJ. 7 C

ingvv connected. with such spout in any desired' or conventional manner. .v The material is.. prevented fr om feeding backwards into i; the open-ingl by the blade 22 which rides on thefperiphery of the-stuffing ,member 1 7, theblades,l8being4 so constructedthat during` their rotation they will move` the blade l by said; feed screw, and means to actuate outwardly and pass` therebeneath.

It will be Seen: that., the, feeding members f i4-incre in. close proximity to` theiuxta- Pased Wallis 0f, thecntainer 8 sa that. a slew f feed diie", to; thewerm drive; of the material. @wards-.the discharge Opening 9- .is .brought about.. n

It will nowbey apparent that I v have devised. a nevel Liset 1v which. embediesytheefeatnreszotadran... .l as; desirable 1n; statement., ef; theA A, tion and the alcove description, and while I h a ve, in the present instance, shown and described any embodiment thereof which will vbodiment is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacriicing any of its advantages. Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is :rk f
